Map depth offset. I know I'm missing it, but...

[Randall53]

I can't find how to change the water depths of the display maps. I'm using the ultra, even though my lake is has not been surveyed, but we have a 6' difference from winter pool and summer pool. It was really easy on my cheap HB I had before. I can't seem to find it on my 93sv. If someone would kindly point me to it, I'd be much appreciative.

Dynamic Lake Level with the Ultra card only functions on the 13,000 or so "HD" lakes (those lakes with 1-foot contours). Given what you said, seems like your lake is not HD.
